ROLLING-=DIE MACHINE.

SPECIFICATION forming part of Letters Patent No. 396,361, dated January 15, 1889.

Application filed April 2'7, 1888. Serial No. 272,076. (No model.)

To all whom it may concern.-

ie it known that I, \VILLIAM II. JOHNSON, of Racine, in the county of Racine and State of \Visconsin, have invented new and useful Improvements in Rolling-Die Machines; and I do hereby declare the followingto be a full, clear, and exact description of said invention, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in rolling dies for cuttin and compressing metal.

In the drawings, Figure 1 represents a side view, and Fig. 2 a top view, of a die-machine containing my improved form of roller-dies. Fig. 3 represents a top view of one of the dieblocks removed from the machine. Figs. 4: and 5 represent several forms of dies made in the interchangeable convex surfaces of the die or face blocks which. are used for cutting or pressing out the various forms of metal. Fig. (3 represents an end view of the machine. Fig. 7 is a detail.

The mechanism by which my roller-dies are operated is represented in connection with a gang-punch with which it is adapted to be 0perated. The gang-punch mechanism does not, however, form any part of the present invention.

In the drawings like parts are represented by the same reference-lotters throughout the several views.

The support lug-frame of the machine consists of two longitudinal bed-plates, A A, sup ported on legs B I), and rigidly connected to gether by cross -pieces 0. Projecting upwardly from and supported on the bed-plates A A are standards D D, in the top of which the transverse driving-shaft E has its bearmgs.

F F are driving-pulleys.

G G are flywheels, and H H are pinions, all of which are fastened to the driving-shaft E. The pinions H H mesh with the spurwheels I I, which spur-wheels are loose 011 the transverse shaft J. Shaft J has its bearings on the standards D I). The hubs K K, integral with the spur-wheels I I, are provided with recesses u a and projections b I), alternately fitted and adapted to mesh with corresponding recesses, c c, and projections cl D by pivots I I.

d on collars L L, which collars L are splined on the shaft J in the ordinary manner. The collars L L also have each an annular groove, 2, about them in their peripheries, in which the bifurcated ends 'of the levers M M operate. The levers M M are centrally pivoted on the top of the supporting-standards N, and at their ends opposite the grooved collar L are pivoted to the outer ends, respectively, of the toggle-arms O O, which toggle-arms at their inner endsare pivoted to the horizontal endwise-moving rod P. The rod is supported and slides in the top of standard N, and standard N is supported rigidly on the frame of the machine. .The rod P is provided with. handles at both ends, whereby it may be actuated at either end of the machine. It will be understood that by moving the rod endwise motion is communicated by and through the arms 0 O and levers M M to the collars L L, whereby said collars are thrown into and out of gear with the hubs K K, whereby the shaft J will be thrown in or out of gear with the driving mechanism.

As shown upon the right in Figs. 1. and 2,.

the dies by which rods and bars of metal are pressed into the various shapes desired are connected with the shaft T by two cranks, A A, and two pitnien, B B. To the outward ends of the pitmen ll 13 is pivoted a reciprocatin cross-head, (1, which is arranged transversely to and rests upon the bed-plates A A of the machine.

I) D are the die-blocks, which are pivoted at their outer ends to the stationary plate E upon the vertical trunnions F F, which plate E is arranged parallel to the cross-head C and is rigidly at'fixed to the bed-plates A A. The die-blocks D I) are both in like manner connected at their inner opposing ends to the cross-head C by the connecting links or bars G l. The bars G ii" are connected to the cross-head C at equal distances from its center by pivots H H, and to the blocks D Thus it is obvious that as the shaft T rot-ates a reciprocating mot-ion is communicatedtherefrom, through the cranks A A and pitmen B B, to the cross-head'C', and from the cross-head C an oscillating motion is connnunicated to the die-blocks D D through the links G G.

The die-blocksDD are each provided with removable dies J J, having corresponding convexed surfaces which conform to a circle described around the supporting-pivots F F, respectively, whereby it is obvious that as the dies turn on their respective supportingpivots F F their faces may be moved in contact or in close proximity to each other the entire length of their convex surfaces, whereby the metal rods or bars introduced between them are uniformly pressed by contact with their opposing convex surfaces. The dies of face-blocks J J "are bolted firmly to the dieblocks D D by screws or bolts K K. The length of the bolts K K is such as to permit of a slight variation in the adjustment of the dies as may be required to make the two dies co-operate properly together, and in case the dies are adjusted out of contact with the blocks thin pieces of sheet-metal filling may be interposed in the spaces between such parts.

To provide for pressing metal of varying thicknesses, the journal-bearing L of one or both of the blocks D may be made adjustable, as shown upon one side of the machine in Fig. 2 and in Fig. 3. hen desirous to adjust the blocks D farther apart, the adj usting-bolts M M are turned outward, and one or more pieces of filling are inserted at a between the journal L and the cross-piece N of the block,when the screws h M are again turned down firmly in place against the journal-bearings. Thus by inserting or withdrawing the pieces of filling a nice adjustment of the opposing surfaces of the dies may be attained. If desirous to simply flatten the metal or bars, die-blocks having plain surfaces are employed. If, however, any peculiar form of barb or point or other metallic thing is desired, the dies are formed accordingly, as indicated in the four different forms of (lies shown under Figs. 4 and 5.

O O are adjusting-screws by which the position of the die-supporting blocks are adjusted. The screws 0 0 have screw-threaded bearings in the upward-projecting lugs P P of the frame and bear at their inner ends against the opposing edge of the plate E, whereby as the screws are turned inward or outward the plate E and the dies thereon are moved in either direction, as desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. I11 a die-machine, two segmental oscillating die-blocks having opposing convex surfaces respectively pivoted to a stationary support, in combination with each other and with operating mechanism adapted to communicate an oscillating movement to both of said dies simultaneously, substantially as and for the purpose specified.

2. The combination, in a die-machine, of two rolling die-blocks, D D, each provided with interchangeable adjustable face-blocks J J, die-retaining pivots F F, connectinglinks G G, head-block C, pitmen B B, cranks A A, shaft T, and a chain of gears connnun'icating therefrom with the driving mechanism, substantially as and for the purpose specified.

The combination of the driving-shaft J, the thereon-revolving spur-wheels I I, provided with notched hubs K K, and the grooved collars L L, provided with teeth or lugs d d, levers M M, centrally pivoted on standard N and provided with bifurcated ends riding in the grooves in collars L L, the toggle-arms O O, and reciprocating rod P, supported and riding in the top of standard N and provided with handles, substantially as and for the purpose specified.

4. In the die-operating mechanism herein described, the combination of the shaft T, geared with the operating mechanism of the machine, cranks A A, pitmen B B, reciprocating cross-head C, connecting-links G G, communicating between the cross -head C and the oscillating die-blocks D D, and the convex removable dies or face-blocks J J, affixed to the opposing ends of the die-blocks D D, substantially as and for the purpose specified.

5. The combination of the shaft T, geared with the operating mechanism of the machine, cranks A A,pitmen B B, cross-head O,pivots H H, connecting-links G G, die-blocks D D, interchangeable die-blocks J J, having opposing convex surfaces connected with said blocks D, and adjustable journal-bearings L L, secured in said die-blocks D and adapted to operate on the die-supporting pivots F F, all substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
